Assignment of Icon (Symbol) - (Font Awesome)

Assignment of Icon (Symbol) - (Font Awesome)

I notice again and again that the assignment of icons/symbols is not structured.

For friends and groups you often have the same "\f0c0".

You can see an example in the photo. For private pages and groups the symbol for people is displayed. Normally there should be a lock. See photo.

Please always use a different icon for friends - groups - private - users and so on. And not for groups and friends the same icons.
And also not for private once a lock and then again a user icon.

Thanks
